To aZZ whom it may concern Be it known that 1., HARRY LrrvAK, subj ect of the Government of Russia, citizen of the United States, and resident of the city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bed- Springs, of which the following is a specification.

This invention relates tobed springs. One of the objects thereof is to provide a bed spring which may be readily foldable when not in use or with the bed-stead.

Another object is to provide a bed spring with means for adjusting the same for maintaining the proper tension on the spring and for eliminating the sag therefrom.

Other objects of this invention will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claim.

In the accompanying drawings, in which is shown one of various possible illustrative embodiments of this invention,

Figure 1 is a partial plan viewof a bed spring embodying this invention;

Fig. 2 is adetailed cross-sectional view on line 2-2 of Fig. 1 showing the transversely hinged member and the means for adjusting the tension in the spring.

Fig. 3 is a partial plan view of a modified form of bed spring embodying this inven tion; and r Fig. 4 is a longitudinal cross-sectional view of the bed spring shown in Fig. 3, when partially folded.

Referring in detail to the drawing, the bed spring embodying this invention shown in Figs. 1 and 2 is seen to comprise the usual wire netting 10 secured at the ends to the attaching and supporting members 11, 11 provided with the usual coil springs 12 for attaching the bed spring to the bed stead. The spring body is divided at its midsection by a pair of transverse supporting members 13, 13' to one end of which are secured the respective halves of the spring body. These members 18, 13 are spaced apart as at 14 and extending between said members across said space 14 are turn buckles 15 adapted to I i specification. of Letters Patent.

1920. Serial No. 398,077.

19 is in the position shown in Fig. 1, a substantially smooth and continuous surface is provided to bridge the space 14:. As will be readily understood when it is desired to adjust the tension in the spring to take up sag or for other reasons the cover 19 is simply swung on its hinges thus allowing ready access to the turn buckles. If desired the turn buckles may be manipulated to separate the bed spring into its two halves.

In the modified form shown in Figs. 3 and 1, the spring body is divided longitudinally into halves 20,20 secured to separate attaching and supporting members 21 21. These halves and attaching members are foldably securedtogether as by means of hinges 22. The spring may thus be folded longitudinally when not in use as for shipment, or when in use with a foldable bedstead. To provide for adjustment of the tension as hereinbefore described in connection with the embodiment shown in Figs. 1 and 2, the end rails 21, 21 are provided with turn buckles 23 similar to turn buckles 15, these turn buckles 23 serving at the sametime as the means for attaching the spring to the bedstead.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

It will thus be seen that there is provided apparatus in which the several objects of this invention are achieved and which is well adapted to meet the most severe conditions of hard practical use.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent A bed spring comprising a divided spring body of woven wire mesh, cross pieces se- Patented ec. 6, 1921.

cured to the end ortions of the divided portions of said spring body, said cross pieces having resilient means adjacent to the head and foot of the bed for attachment to a bed and threaded members in opposed operative relation at the free ends of the cross pieces for joining and separating the dividedspring portions and forpermitting an adjustment of the space between said divided spring body portion so as to take up an slack or sag therebetween or between sai portions and thesid'es oft'hebed, and a hinged cover forthe s ace and threaded members.

' Si "e at New York city, in the county of New ork and State of New York, this 23rd day of June, A. D. 1920.
